Despite GTL´s contentions that two Securus patents should be invalidated, the court sided with Securus on these two patents: US Patent No. 7,529,357 — which discloses a system and method for controlling inmate access to a telephone carrier network using voice over internet protocol data packets exchanged between call processing gateways; and US Patent No. 8,000,269 — which discloses systems and methods for processing voice over internet protocol calls originating within a prison facility that include an unauthorized call activity detector.
